COOLING ARRANGEMENT.

Applicationfiled June 21, 1923, Serial No.

My invention relates to cooling systems adapted particularly forelectrical devices of large power, such, for example, as mercury arcrectifiers; t is the object of my invention to provide an improved watercooling system suitable for power devices and;

similar installations, which requires no oversightand has nocomplicated; and expensive provided a simple, eiiicient cooling outfitfrom the rectifier and delivered to .a containof low cost whereby thecooling fiuidis circulated in parallel by a single pump between thedevice to be cooled, for example, a recti-' fier, and a heat dissipatingdevice such for example, as'a spray cooler.

The accompanying drawing illustrates my invention diagrammatically. V 1r r This drawing shows a tank 1 from Which water is drawn continuouslyby a pump '2 through a, duct'3, and delivered under pressure to aconduit 4, one branch 5 of which terminates in a nozzle 6 ifrom whichpart of the Water drawn from the tank 1 is returned as a fine spray orfountain causing an energetic cooling of the water. At the same timeanother part of the water is delivered by a duct 7 to the mercury arcdevice '8 which is to be cooled. This duct also may terminate in anozzle 9 for delivering a spray. The water which has become warmed bycontact with the heated device 8 returns by a conduit 10 to thetank 1. vp

This arrangement has several advantages.

By delivering only part-0f the water. from the o pressure pipe 4; to therectifier and returning the rest as a spray, it is possible in a giventime to produce an energetic cooling. F n thermore, the circulation ofwater in thefrec tifier is entirely independent of'the heightv ofthe-water in the main container and" no such control devices arerequired as would be necessary were the cooling water taken direct er ata higher level. V I may be desired to be cooled can be supplied tank, apump; connected withthe tank, and means for delivering cooling fluidas'a spray to said device to be cooled'and a'return pipe '0 4 646,985, ain Gama August, 10,1i9 22;
